5 Claims.

This invention relates broadly to a packaging machine and more particularly to a device for placing a disk-shaped rubber article in a tubular wrapper.

'I'he device of the present invention is particularly useful in the packaging of collapsible articles. Although the device is described herein in conjunction with the packaging of thin, tubular, rubber articles, closed at one end, with the side walls thereof rolled upon themselves to a point adjacent the closed end wall, it is not intended that it be so limited for the invention can be used for packaging numerous other types of articles. The wrapper for the article is preferably an open ended tubular member relatively smaller in diameter and axial length than the diameter of the article so that when the article and wrapper are assembled a portion of the article extends beyond the ends of the wrapper.

By the present invention there is provided a packaging device which includes, generally, a wrapper feeding assembly for conveying to and introducing tubular wrappers into successive chambers of a continuous transfer magazine as they are presented to the wrapper feeding assembly, a receptacle for the articles and reciprocating means which pass through a wrapper, grip an article and draw it into the wrapper.

This invention relates generally to the type of device shown and broadly claimed in the cepending application of Peter Jost, Serial No. 181,354 filed December 23, 193'?.

In the drawings accompanying and forming a part of this specification, wherein similar reference characters denote corresponding parts:

Figure 1 is a fragmentary perspective view of a packaging device embodying the features of the present invention,

Figure 2 is a fragmentary top plan view of the device of Figure 1,

Figure 3 is a fragmentary longitudinal sectional view of the apparatus shown ln Figure 1,

Figures 4 and 5 are fragmentary sectional views taken on the lines 4-4 and 5 5, respectively, of Figure 3.

In the drawings there is illustrated apparatus embodying the present invention, including a substantially rectangular bed frame Il) supported on a frame-work comprising longitudinal members Il and transverse members I2. Adjacent one end of the top of the bed frame is an elongated slot I3 having ways Il mounted along each side thereof adapted to receive a reciprocating slide block I5. A bolt I6 threaded through the block I5 and extending through the slot I3 operatively connects the block to suitable reciprocating means, to be described, positioned below the top of the bed frame Ill. The reciprocating block I5 has mounted thereon a pair of elongated spaced transfer fingers I1 and Il. The finger Il is mounted in xed position whereas the finger I8 is movable relative to the finger Il. Mounted in the path of the transfer fingers is a roller I9 engageable with the nger I3 and operable to effect the closing of the outer ends of the transfer fingers.

Positioned adjacent the end of the outward stroke of the reciprocating transfer fingers is a cylindrical receptacle 2i for receiving, in stacked relation, disk-shaped articles A to be packaged, as they are discharged from a continuous conveyor 2|. An opening 22 is provided in the wall of the receptacle 2U through which the transfer fingers may enter the receptacle, grip an article and withdraw it from the receptacle.

Extending transversely of the bed frame I0 and mounted on the top thereof adjacent the receptacle 2li is a track 23 upon which rides a continuous chain 2l having a plurality of transfer members 25 secured thereto. Each of the members 25 is provided with an elongated slot constituting a magazine chamber 23 into which empty tubular wrappers are fed from a wrapper feeding assembly. Movement of the chain is controlled by sprockets 2l and 2l secured on shafts 29 and 30, respectively, rotatably mounted in suitable bearings disposed along each side of the bed frame I0. A plate 25a is provided to cover the members 25 at the point where the transfer fingers are adapted to move through the magazine chambers of the members.

The empty tubular wrappers are conveyed from a suitable hopper (not shown) to charging position by a feed tube 3| which serves to deposit successive wrappers into the end of a trough 32 denned by ways 33 secured to the top of the bed frame II). Slldably mounted in the ways 33 is a plunger 3l which is operatively connected to the slide block IB by link 35. The plunger 3l ls adapted to introduce the empty wrapper disposed in the trough 32 into the chamber 26 of the transfer member 23 aligned therewith as the slide I5 moves on Its outward stroke. A plate 3B secured to the top of the bed frame covers the magazine chambers 2B at the point where the wrappers are charged into the chamber by the plunger 34.

Supported beneath the top of the bed frame I0 are a pair of spaced bearings 21 and 33 having Journalled therein a cam shaft 38 upon which is keyed a spiral cam element lli. The cam shaft 29 may be rotated by any suitable means (not shown) 'Ihe spiral cam 49 is positioned on the shaft 29 below the slot I2 and has formed therein a groove ll in which rides a cam follower I2 freely mounted on the end of the bolt I6. Reciprocation of the slide block I5 together with the transfer fingers carried thereby is actuated by the cam 49. one revolution thereof effecting a complete reciprocation of the slide block l5.

The shaft 29 also has cam I3 mounted thereon which engages with a cam follower Il carried on the lower end of a slldable rod l5, the other end thereof carrying the roller I9. 'I'he cam 42 is so formed and positioned on the shaft 39 that the roller I9 actuated thereby urges the transfer linger I8 toward the nnger I1 at the end of their outward stroke and during the return stroke of the fingers, releasing the finger I9 just prior to the end of the return stroke. to release the article disposed between the ends of the fingers I1 and I9. The release of the article by the fingers is so timed that the article is deposited within a tubular wrapper positioned in one of the magazine chambers 29 of the members 29.

The mechanism for moving the continuous chain 2l along the track 29 to bring successive transfer members 25 into position for receiving a tubular wrapper and for inserting an article in a wrapper disposed in one of the members in timed relation with the reciprocation of the transfer nger includes ratchet wheels i9 and 41 mounted, respectively, on the shafts 29 and 29. Rotation of the shaft 29 is effected through an elongated pawl I9 engaging the ratchet wheel I6. The pawl Il is pivotally connected to the end of a pivoted lever arm 49 supported from a longitudinally extending supporting member Ell by bracket 5I. Mounted on the member 5B is a housing 52 in which is slidably mounted a slide block 59 the lower end of which is operatively connected to the free end of the lever arm I9. The upper end of the rod 62 is formed with a cam follower 5l which engages a cam element 55 mounted on the shaft 39. The ratchet wheel 41 mounted on the shaft 99 and engaged by a pawl 81 maintains a predetermined movement of the chain 24 during each rotation of the cam shaft 29 and assures that the magazine chambers are properly aligned with the transfer fingers. Suitable links 59 and B9 operatively conneet the pawl 81 with the block 52 so that when the block l2 is depressed the pawl 51 is disengaged from the ratchet II to permit the pawl 4l to move the ratchet wheel 49 to rotate the shaft 29 thereby bringing the successive magazine chamber into alignment with the path of the reciprocating transfer fingers.

The operation of the apparatus described hereinabove may be briey summarized as follows:-

'111e receptacle 29 and the magazine chambers 29 of the members 25 between the wrapper feeding assembly and the transfer fingers are filled, respectively, with articles and tubular wrappers. The cam shaft 29 is continuously rotating, and at the beginning of a cycle of operation, the slide I5 and transfer fingers I1 and Il carried thereby are at the extreme left as viewed in Figures l, 2 and 3. Rotation of the cam I9 moves the slide to the right causing the transfer fingers I1 and I8 to traverse the magazine chamber 29 aligned therewith and a tubular wrapper in the chamber. and enter the receptacle 29 through ythe opening 22. The ends of the fingers I1 and Il are open as they enter the receptacle I. 3nd positioned,

respectively. above and below the periphery of the lower-most article of the stack disposed therein. As the slide is moved on its outward stroke the plunger 34 operatively connected thereto lifts the end of the feed tube 2i and further movement of the slide causes the plunger 34 to project the empty tubular wrapper disposed in the trough 22 into the magazine chamber 29 aligned therewith.

At this point, which is the end of the outward stroke of the slide block I5, the cam Il acts through the follower il, rod li, and roller I9 to move the finger I9 toward the linger I1. This movement of the roller I9 causes the ends of the transfer lingers i1 and Il to grip the edge of an article in the receptacle. The cam Il then starts the return stroke of the slide I9 during which movement the cam I3 maintains the fingers in gripping relation with the article. 'I'he transfer ngers I1 and I9 draw the article from the receptacle 29 and into the tubular wrapper disposed in the magazine chamber 26. The release of the article by the fingers is so timed that the article is substantially centered within the tubular wrapper. Immediately following the release of the article the cam element 55 is brought into play to depress the block 52 which eects the release of the pawl 51 from ratchet l1 and pivots the lever arm I9 thereby causing the pawl 4B to rotate ratchet I6 on shaft 29 which in turn effects movement of the chain 2l to bring the magazine chamber of the succeeding transfer member 25 into alignment with the path of travel of the reciprocating transfer fingers. The device is then in position to repeat the foregoing cycle of operation.

Having thus described the invention what we desire to obtain by Letters Patent is defined in the appended claims.
